How to remove Gear from stock Clutch Basket?

[Phat Bastard]

Got the clutch basket out of the bike, now have to remove the gear from the basket! Do not want to mess up my drive gear. I did not realize the rivets were steel.

OK, do you drill out the rivets or grind them off?
What size of drill?
Do you drill from the basket side or the gear side?
If I drill or machine the head of the rivets off on the basket side, how do I get the rest of the rivet out of the gear?

Please Help!

I ground out the rivets from the inside of the basket and then used a punch to pop the rivets out the back of the gear. %#%$ of a job!
